  • Submetering is using meters to measure parts of
    total load measured by the Electric Utilitys
  • Master Meter/s
  • Usually
  • Submetering is encouraged by the state and
    federal governments, US and Canada
  • The load side of the Master Meter, owned by the
    Electric Utility, is the POCC
  • The Submeters do not measure the total load seen
    by the master meter, e.g., Meters do not measure
    their own load

POCC Utility Billing Point
  • Submetering is the measurement and billing of
    electricity use in separate units of a master
    metered building. The Submeters are owned by the
    building owner - the utility continues to read
    the buildings master meter and issue a single
    billing to the owner.
  • Building owner buys energy at bulk rate and bills
    tenants for usage instead of utility rate is
    guaranteed to be lower than residential rates in
    most states.
  • Submetering is often linked to Building Energy
    Management System to improve efficiency
  • Target Customers
  • Condos
  • Co-ops
  • Large Apartment Buildings

5
Why Submeter? Residential
  • Submetering Saves Energy. An analysis of
    Submetered buildings (where data has been made
    available) conclusively illustrates that annual
    savings of 18-30 of total tenant electrical
    consumption was achieved in the first year.
  • Submetering Energy Savings Persist Over Time.
    Submetering savings have proven to be
    maintainable over long periods of time as
    demonstrated in a number of studies. Some likely
    reasons are that (a) conservation is reinforced
    by the resident's receipt of an electric bill
    and (b) residents will invest in efficiency
    (e.g., more efficient refrigerators and lighting)
    because they will reap the benefits directly.
  • Approximately 60-70 of Tenants Benefit from
    Submetering. The only tenants who fare worse
    under Submetering than under other means of
    allocating electric cost are those who use
    excessive amounts of electricity. Those residents
    who find that their electric bills are excessive
    have the ability to reduce cost by reducing
    consumption.
  • Submetering is Fair. Submetering simply restores
    the "user pay" concept. Tenants who leave windows
    open and leave on lights will pay for their
    actions or change their habits.
  • Submetering Benefits Owners - Submetering largely
    eliminates a volatile, variable, and
    difficult-to-control factor from a building's
    operating budget. Owners can better predict costs
    when the only electricity usage to be considered
    is for common areas under management control.
    Submetering is a competitive tool for owners -
    submeters lower energy costs.

  • Submetering is the measurement and billing of
    electricity use in separate units of a master
    metered building or group of buildings. The
    Submeters are owned by the property owner. The
    utility continues to read the master meter and
    issue a single billing to the property owner.
  • The Property Owner buys energy at bulk rate and
    bills tenants for usage.
  • Commercial Submeters Measure both Energy Usage
    and Demand, and occasionally Time-of-Use (TOU).
    The ability to link to an Energy Management
    System is often required.

    Submetering

Plus Demand Management
9
Why Submeter? Commercial
Demand Is the average rates of energy usage
during a time period, typically 15 or 30 minutes,
e.g., 200 kWh for 15 min/15 min 800 kW Demand
  • Manage Demand Charges
  • Commercial and Industrial Electric Bills include
    large Demand Charges based on Peak Usage during a
    month.
  • New Peak Demand charges typically are carried for
    a year.
  • Maximum Demand can be changed just by changing
    when loads are started.

Submetering Exposes the Sources of Demand Peaks

Economics of Submetering
Example Air Force Base Sees Energy Savings Take
Off ACHM News Situation Los Angeles Air Force
Base, 150-acre Government offices, research and
development laboratories, military housing, and
other facilities. Accurate energy metering was an
issue at the site where only one master utility
meter measured energy usage for the entire base.
Energy Manager, Ed Wilson, says, We knew we were
using a lot of energy and we were trying to
determine where it was being used and at what
time of day. But, we really had no idea which
buildings were using more or less energy.
Project 36 meters were installed at the
service entrances of 14 main buildings, totaling
about 100,000 square feet. Data was collected
from the submeters and then relayed to the
energy managers computer. The submeters store
information for up to 36 days in 15-minute
increments and maintain data in case of a power
interruption.
Payback Less than three years after the Bases
submetering system was implemented, energy
consumption decreased more than 27 percent from
the established 1985 baseline. Utility costs
decreased 23 percent from an established 1990
baseline during a period in which electricity
rates increased by 4.5 percent. Overall, Los
Angeles AFB has saved more than 1 million
annually on its utilities, and is likely to save
more in Californias tightening energy market.

POCC Utility Billing Point
  • Submetering is the measurement of key pieces of
    the total energy used by a business so that the
    pieces can be benchmarked and energy trends
    monitored.
  • Industrial Submeters Measure Energy, Demand, and
    often Time-of-Use (TOU) and Load Profile
    Recording
  • Industrial Submeters also often measure the
    Quality of Power delivered by the Electric Utility
  • Target Customers
  • Process Industries
  • Industrial Facilities
  • Grocery Stores
  • Businesses with Energy Management Systems

12
Why Submeter Industrial
  • Allocate Energy Costs - Submetering allows
    facility owners to equitably distribute actual
    energy costs to departments or tenants, to assign
    accountability to energy users and to provide
    incentives for energy users to reduce costs.
  • Benchmarking To Discover Opportunities For Energy
    Efficiency Improvements It is possible with
    Submetering to measure who is using energy, how
    much they are using and when it is being used.
    That information can then be used to pinpoint the
    cause of utility demand charges and compare
    energy efficiency with similar users.
  • Lowering Energy Costs - Knowing energy-use data
    is critical for negotiating energy procurement
    contracts and is a powerful visual analysis tool
    to explain consumption and demand patterns.
  • Measure And Verify Energy Conservation Projects -
    Submetering can be used in audits before and
    after energy upgrades to measure how much energy
    a project is saving.
  • Identify Performance Problems In Processes and
    Equipment - A proper Submetering setup can signal
    excessive energy use with specific pieces of
    equipment, systems or processes.
  • Limit Demand - Optimizing system performance
    requires use of real-time energy data to indicate
    how much energy is being used at virtually any
    time of day. Submeter data can also forecast
    building demand and can help consumers to
    implement routines that curtail use. Linking
    Submetering with Energy Management Systems
    provides a much higher level of control.
  • Identify Power Quality Problems Monitoring
    Power Quality Protects Equipment and improves
    up-time
  • Verify The Accuracy of Utility Bills

Submetering Provides the information Needed to
Control of Energy Costs
13
Demand Reduction Example
  • A Light Manufacturer who operates on 2 shifts.
    The typical electricity cost is about 150,000
    per year the facility was paying, in a typical
    summer month, 12,000 electricity. (All figures
    are rounded)

New Peak Demand 430 kW _at_ 140PM
